    Abstract: In a method of forming an epitaxial layer, a first plasma may be generated from a first reaction gas in a first region. The first plasma may be applied to a second reaction gas provided to a second region isolated from the first region to generate a second plasma from the second reaction gas. A blocking gas may be injected into the second region toward an edge of the substrate to help prevent the first plasma and the second plasma from being horizontally diffused. The first plasma and the second plasma may be applied to the substrate to form the epitaxial layer. Thus, the epitaxial layer may be formed at a temperature relatively lower than a temperature in a heating process.
